Got a small problem with the 996, as previously found by Porsche a few weeks ago, since the service last week its got a little worse.



Basically the MAF is playing up (either needs a new one or needs cleaning)

Going to give the MAF a good clean this wk end but if i need to replace it, anyone know how much a new one is?

Also, anyone else had this? its a stuttering when you try to accelerate in a high gear at low revs.

I'm aware it could be an air leek, any common areas for air leeks which would cause this?

thanks

Lee

i would def say it was an air mass meter. they are about 250 quid with half an hour labour - btw did you go to an OPC?

i thought it was, i had this on my s4 a year or so ago and it felt the same.

Yeh, the cars been to two OPCs, one in kent quoted 450 for supply and fit and hatfield didn't quote me a replacement price, instead they quoted an investigation only, subject to more costs of 116.

I can fit one no problem, its dead easy, i will give the original a good clean in alcohol this week end and see if that works, if not i'll be ordering the part.

TBH, not really been impressed with either OPC, the original quote for the service was 625 at Hatfield plus 100 for a set of new locking nuts (40 suply 60 fit), ended up with a bill for nearly 1000, and then managed to negotiate it down plus 10% discount from being in PCGB resulted in 856. Apparently spark plugs and belts aren't included in a full "major" service. I'd hate to see what they replace if it was a "minor" service.



Another question, do they accept the old unit in exchange for a reconditioned MAF? Audi did this with my s4 one.

Plus i've had varying quotes for the cam seals need replacing (tiny leak but needs doing for warranty) 500 kent or 886 in Hatfield (i could go down and stay in a nice hotel and have it done Wink )

i think i'll need to negotiate ;-)

It seems that they don't spend the time getting the quote exactly right and end up charging more anyway and most customers I bet end up paying up regardless.

Shouldn't moan too much, they did pick my car up and drop it home and the engine feels loads better after the service.

MAF is not an exchange unit. plugs and belts are part of 48k service approx 800



is it just the cam covers leaking? does it seem to be coming out the cam cover bolt heads? if so you can just remove the bolts and reseal each individual thread with silicone.

MAF - ok, thanks. 48k service - sounds like I got a bargain then, but looks like they're quotes are not complete.

cam covers - i'm not sure, i personally haven't looked in detail, if it is the bolts how do i undo them? i assume they're at the top of the engine and I can't imagine i can get at them from the back of the car?

thanks for the help, much appreciated.

its a flat six so are on the side - they are just 10mm bolts - do one at a time as the camcover also holds the cams in place

I had to get the RH bank cam cover done in order to get the warranty too. Quoted 550 all in but then they sheared off a head bolt so the precision engineer cost 55 more. However, they looked on the system and saw that the car had a new cylinder head 23 months previously and so it was done for free as all work is guaranteed for 24 months. Result!. So be careful removing the head bolts if you need to!!

thanks for the info phil, will probably leave it to the experts but will have a look over the wk end.



911 doctor - I've just reserved a new MAF (figured my cleaning the MAF probably isn't a good long term fix anyway) at Hatfield OPC and they're going to charge me 275.80 plus VAT (324.06), am I getting ripped off? or is this the standard price?

Haven't paid anything yet, going to pick it up on saturday morning.

i know, but i paid it on the basis that I didn't have the old locking key and hence there was no way I could have got the wheels off. If I had the locking key then fair enough its a five minute job and I'd have done it no problem.

ahhh - ok - they had to remove a set without the key - fair enough.

oh *****, fitted the new MAF today.

Its even worse than it was before!!

Any ideas?

I've checked the air pipe which connects the throttle body to the air box and it appears fine to me. Don't think there;s any air leaks.

Where else should I be looking?

I'm fed up and lost on what to do.

Was impressed with the Hatfield show room though ;-)

the fault was initially picked up using the system tester.

I've book the car in with JZM on the 11th April, the guy sounded honest and he also suggested it could be a lambda sensor.

JZMs labour rate is 55 compared to 90 odd at the OPC, i'll let them figure it out and sort it all out. Can't wait to pick it up all finished.

It'll also be good to gauge the service levels of JZM compared to the OPCs.

My other problem with the car, the supposedly leaking cam seals (not dripping any oil on the floor), JZM was surprised about this, he meantioned that it could just be the green caps on the front. I have no idea what he's talking about, do you? I had a look over the weekend and couldn't see anything, no idea how you manage to see the side of the engine when looking from the back of the car, can't get my massive head in the little gap Wink Porsche technicians must have small heads ;-)

it wont be the green caps - they cover the end of the cams (just plastic seals) they dont tend to leak - i guarantee you it will be coming out of the bolts. its very common
